Since I upgraded my antiquated HTC Magic to the shiny (and slim) Samsung Galaxy S2 I have spent most of my time downloading new games, a significant fraction of which are the so-called "casual games". These games usually cost between $0.99 and $2.99 and are of the Farm Frenzy, Angry Birds and Plants vs. Zombies variety. I tend to download a few, play them non-stop for about a week and then let them languish inside an aptly named "Old Games" folder.
